Figure 8
The structure of 5, showing (a) layers of distorted KO8 prisms formed from the metal ions, the O atoms of water molecules (shown in green) and one carboxylate O atom from each Hhba− unit. (b) The edge-to-face and face-to-face stacking of the Hhba− ligands; note the inversion that occurs within face-to-face pairs. (c) The packing arrangement, viewed along the c axis. H atoms have been omitted in parts (a) and (c). Colour code: K blue, carboxylate and phenolate O red, water O green, C black and H pale pink. |
